PATENT OFFICE- HEATING DEVICE.

SPECIFICATION forming part of Letters i 'atent No. 315,422, dated April 7,1885.

Application filed April 19, 1884.

To all whom it may concern.-

Be it known that I, GEORGE L. LAVERY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Heating Devices, of which the following is a specification.

My invention is an improved heating device whereby the heat radiated by gas, kerosene-oil, or other illuminators can be utilized for heating and warming purposes.

The object of my invention is, first, to utilize the heat radiated by illuminators; second, to afford facility for regulating the temperature of the heater; third, to economize by antomatic means the quantity of illuminating medium.

The heater can be constructed either as stationary or as portable. The accompanying drawing, which forms part of this specification, shows a stationary heater in conjunction with a chandelier, using gas as an illuminator, the radiator being situated in an apartment other than that in which the chandelier is 10- cated.

A is a generator; 13, apipe leading from the top of the generator A to a radiator, 0. Dis a pipe leading from the radiator'O at a point lower than the entrance of the pipe B to the bottom of the generator A. E is arelief or automatic pressure-valve having a graduated arm, L. M is a movable weight attached to arm L, by which the valve E can be adjusted for different pressures as a means of varying the temperature of the heater when desired. The generator A, pipes B and D, radiator O, and valve E are filled with water or other liquid. F is a chandelier; G, one of the burners on same, which can be provided with. a form of burner that radiates heat freely while illuminating. H is a supply-pipe for chandelier F. K is a valve on pipe H, in proper relation with and operated by the relief or pressure valve E.

The operation is as follows: The heat radiated by the illuminator at burner G is im- (No model.)

parted to the water or other liquid in the gen.-

erator A, which, as it becomes warmer, ascends in the pipe B to the radiator O, diflusing heat in the apartment where the radiator 5o is situated, and, becoming cooler, descends in the radiator, and by the pipe D is conducted back to the generator, there to be reheated. When sufficient heat has been communicated to the water to cause the pressure-valve E to 5 5 operate the valve K, the illuminating supplyis diminished and the radiation of heat re-C duced at the burner G. The pressure E being automatic in its action, operatesflthe valve K, increasing the supply when the press ure on the heater falls sufficiently.

As a portable heater, the operation is identical, the construction differing. to allowthe heater to be placed in a frame or table capaa ble of being moved from place to place. I am aware that prior to my invention heaters have been made using heat from gas, l

ator, A, pipe B, radiator O, pipe D, regulating-valve E, all filled with water or other, li-

quid, in combination with a chandelier, F,

whereby is utilized the heat radiated at one or more of its burners, substantially asshowir, and for the purpose set forth.

2. Thecombinationofthe generator A, pipe B, radiator O, pipe D, valve E, all filledwith water or other liquid, the chandelier F, burn-. er G, gas-supply pipe H, and valve K, sub stantially as shown, and for the purpose set forth and specified.

In testimony whereof I have signed my name 8 5 l to this specification in the presence of two subscribing witnesses.
